Review: MeriMoney.com - Cashback & Rewards Website
MeriMoney is an indirect selling website that offers cash backs on purchases.
Online retailers usually provide referral commission when users shop with them through a referral link. MeriMoney shares a part of that commission with end customers resulting in a win - win for all parties. This cashback is independent and is over any other benefit which end website may offer you. Moreover, it ensures complete security as the actual sales are made on the retailer's website.
Though such models haven't been much successful in developed countries, there is good likelihood that this may turn out to be a great success as customers in India have comparatively weaker purchasing power and aspires to get the best value for their transaction.
Conclusion - Though the benefits may be marginal, There is no harm in giving it a try. It's all safe and will add value to your existing transaction.
